JAMES HOULEHAIEOE TOLEDO, OHIO, ASSIGNOR TO GEORGE G. HADLEY AND GEORGE P. MERRILL, BOTH OF SAME PLACE.

WRENCH.

SPECIFICATION forming part of Letters Patent No. 289,347, dated November 27, 1883.

Application filed October 26, 1883. (No model.)

To all whom it may concern.-

Be it known that I, JAMES HOULEHAN, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Wrenches, of which the the required adjustments are obtained.

Similar letters of reference indicate similar parts in both figures.

A is a handle, having the ferrule B. The

shaft D is secured permanently to the handle A. The shaft D is provided with ratchetteeth D D on each side. The teeth on the opposite sides of the shaft D are at different heights, not occupying the same plane at the respective sides. The lower or sliding jaw is shown by a and the fixed jaw by a. The sliding jaw a forms a part of the sliding shank O,which exteriorly is of cylindrical shape, and fits neatly within the ferrule B. The shank O has a longitudinal aperture of square or arrangement of the parts by means of which rectangular cross-section, neatly fitting the shaft D, so as to slide thereon. E E are pawls pivoted at e to the shank O, and are kept in engagement with the ratchet-teeth by the springs F. The pawls are made to engage 0 one or more teeth.

The operation of the wrench will be readily understood. When the lower jaw, a, is to be shifted, the pawls E are pressed against the springs and disengaged from the ratchet-teeth D D, and the jaw moved by hand.

This wrench, in its construction, possesses simplicity and strength, and is easily manipulated to the nicest adjustments.

Having described my invention, I claim ;c

1. The combination, in amonkey-wrench, of a ferrule, cylindrical sliding shank carrying the lower movable jaw, spring-pawls, and stationary shaft carrying the fixed jaw, and hat-'ingserrations at each side, substantially as set forth.

2. Ina wrench, aoylindrical shank carrying the movable jaw, and a stationary shaft car-
